DIAGRAMS. Sony XR-CA 440, XR-CA CA440, XR-CA 430X, XR-CA CA430X, XR-CA CA400

Below you will find brief information for cassette car stereo XR-CA 430X, cassette car stereo XR-CA 440. The XR-CA 430X and XR-CA 440 are car stereos that offer a variety of features, including cassette playback, FM/MW/LW radio, and a 45W x 4 power amplifier. The XR-CA 430X and XR-CA 440 are compatible with a wide range of vehicles and can be installed in either the front or rear of the car.
